Pacific/Apia should not be mapped to meta zone "Samoa"

Description

In metaZones.xml, there are 3 zones mapped to meta zone "Samoa".

However, !Pacific/Apia is 1 day ahead from other two zones since December 30, 2011. Apia skipped one full day (from UTC-11 to UTC+13). Midway and Pago Pago had not been changed and using UTC-11 today.

We probably need a new metazone "Western_Samoa" for !Pacific/Apia with display names "Western Samoa Standard Time" / "Western Samoa Daylight Time".

!Pacific/Apia is currently the golden zone for metazone "Samoa". This should be also changed to Pacific/Pago_Pago.

After reviewing some descriptions, we probably should go the other way. That is,

  • Metazone "Samoa" for Samoa (formerly known as Western Samoa) - Apia

  • Create a new metazone - probably " American_Samoa" - for !Pacific/Pago_Pago and !Pacific/Midway

Replying to (Comment 1 yoshito):

After reviewing some descriptions, we probably should go the other way. That is,

 

  • Metazone "Samoa" for Samoa (formerly known as Western Samoa) - Apia

  • Create a new metazone - probably " American_Samoa" - for !Pacific/Pago_Pago and !Pacific/Midway

 

Further investigation changed back to my proposal to original one.

American Samoa (Pago Pago) uses UTC-11:00. In the tz database, its abbreviation is "SST" and comment - "Samoa Time". It looks this is widely spread, and many Web sites including wikipedia refers the time used in American Samoa as "Samoa Standard Time".

On the other hand, Independent State of Samoa (Apia) moved from UTC-11:00 to UTC+13:00 a few years ago. The tz database uses abbreviation "WST", which means "Western Samoa Time". However, the term "Western Samoa" as the country name is no longer used. So, "Western Samoa Time" is not appropriate for the time zone name.

With the given facts above, the metazone "Samoa" should be used for American Samoa (Pago Pago), and use a different name for Independent State of Samoa (Apia). Because "Western Samoa Time" is not appropriate and "Samoa Time" causes a conflict with the metazone "Samoa", I propose to use "Apia Time" as the name (with no short abbreviations) in CLDR.

So, the updated proposal (back to original + some modifications)

  • Add a new metazone "Apia" with long display names "Apia [| Daylight|Standard] Time"

  • The golden zone mapping for the existing metazone "Samoa" will be changed from "!Pacific/Apia" to "!Pacific/Pago_Pago"

  • Change zone to metazone mapping for "!Pacific/Apia" to mz "Apia"
